Factorio and Windows 11

[Delen22]

Hi,

I've been playing Factorio and Space Age on the same computer for about 3 years.
Recently the computer has updated itself to Windows 11 and I can see some performance issues when playing FactorioSA.

The most common one is that, periodically, the game drops from 60 to ~10 FPS for some time, maybe 30-60 seconds, and suddendly it goes back up to 60/60 with no apparent reason.

I initially though that my base was getting too big, but even with a early game (not even left Nauvis) this happens.

I have some mods too, but i do not think they could be the cause: Car finder, even distrib, helmod, Noxys Swimming, Power grid comb, Rate Calculator, Squeak through, task list, vehicule snap and water fill.

It seem to be even worse when Chrome is running, but happens no matter what.

A quick check in the task manager does not show any lack of memory or CPU.
I also moved the game folder that was sync with OneDrive in case the changes in game files were trigerring OD too much.

I try to read the debug info in game, something that was linked to V-Sync (flip) but even turning V-sync off did not change the result.

Does anybody has any ideas on what could be the cause of the problem? What could be done to improve the situation?

I could provide more information if needed to help debug or isolate the issue.

Thanks in advance to all of you.

The thread Linux: Factorio 2.0/SA drops to 30FPS intermittently (sometimes UPS drops too) had similar symptoms due to CPU getting bored and throttling down.
